The last such flight was recorded on March 21, and since then drones have flown only in Romanian airspace. It is assumed that the suspension of flights was due to fears that drones could be targeted and destroyed, especially given the high cost of the Global Hawk model.
The Reaper drone incident occurred on April 14, and there were fears that the more modern Global Hawk might suffer the same fate. Before the suspension of flights, drones were making an average of up to ten reconnaissance flights per month in the region of the Crimean peninsula.
